WINDOW.

SPECIFICATION forming part of Letters Patent No. 532,043, dated January 8, 1895.

Application filed April 1 To all whom it may concern:

, Be it known that I, JOHN K. FAGAN, of West Superior, Douglas county, lVisconsin, have invented certain Improvements in VVindows, of which the following is a specification.

My invention relates to improvements in window sashes, the object being to provide a sash which when locked will always fit tightly in the casing, but when unlocked may be raised and lowered freely.

To this end my invention consists in forming the window casing against which the sash is fitted, in beveled form, contracted outward, the edges of the sash being similarly beveled. I also secure elastic weather strips to the edges of the sash which serve to make the joints between the sash and easing practically air tight. The sash is supported in the ordinary manner upon weighted cords and hangs normally slightly away from the easing, so that it will run freely up and down, but when closed is pressed outward wedging closely against the casing by means of cam looks upon the casing, the upper and lower sash being interlocked in the ordinary manner. I also preferably form the sash to receive two panes of glass with an air space between, so as to make a single sash serve the purpose of a storm window.

My invention further consists in the construction and combination hereinafter described and particularly pointed out in the claims.

In the accompanying drawings forming part of this specification, Figure 1 is a horizontal section of a window fitted with my improved sash, showing the beveled faces of the casing and edges of the sash, and the weather strips set into the sides of the sash, and also the double glass in the sash. Fig. 2 is a partial vertical section of the same. Fig. 3 is a detail plan view of one corner of the sash, and Fig. 4 is an enlarged sectional detail of the same.

In the drawings the window A is provided with the beveled outwardly contracted casing 2 against which the sash 3 and at slide. The sides of the sash are beveled at the same angle as the casing, and fitted into grooves Serial N 70,156. (No model.)

in the same are elastic weather strips 5 which bear against the casing. The sash is supported in the ordinary manner by means of weighted cords 6 running over pulleys 7', and

hung so as to normally swing inward sufficiently to clear the casing, and therefore can be readily raised and lowered, a sufficient space being allowed between it and the stop 8 for the purpose. The sash when in closed position is pressed outward by means of cams 9 pivoted to the casing and bearing against the inner face of the sash. The top of the upper sash 3 is similarly beveled to fit against the beveled casing strip 10 at the top of the window against which it is forced when closed, by means of a suitable lock 11, which serves to fasten the upper and lower sash together in the ordinary manner. In order that the window may be used as a winter protection, I provide on the inside of the sash removable strips or stops 12 set into grooves in the edge of the sash, into which grooves may be fitted an additional pane of glass 13, and there secured by the strips. The window is thereby provided with double panes, having an intermediate air space. The close fitting joints between the sash and the casing and the window so constructed, form an adequate protection against severe cold, making an independent sash fitted to the window unnecessary.

I claim- 1. The combination with the window having the beveled casing, of the window sash similarly beveled and fitted thereto, counterbalancing supports for said sash, and the cam locks for pressing said sash outward in said casing.

2. The combination with the window having beveled casing, of the similarly beveled sash fitted thereto, counterbalancing support for said sash, the elastic strips arranged in the edges of said sash, and bearing against said casing, and the cams for thrusting said sash outward against said casing.

3. The combination with the window having a beveled casing, of the similarly beveled sash fitted thereto,the elastic strips arranged in the edges of said sash and bearing against said casing, the cams for thrusting said sash outward against said casing, and the lock for securing the upper and lower sash together.

4. In a. window, the combination with the beveled casing, of the correspondingly beveled sash fitted thereto, the swinging support for said sash allowing the same to be carried inward from the casing so as to be raised or lowered, and the devices for thrusting the
